Well according to what I know and the amazing plethora of knowledge from wikipedia, Uriah the Hittite was only involved in being indirectly murdered by David by having his men retreat from the front lines so he can be killed so David could have his wife. And I just did a bit of research on the huge Egyptian, not finding anything, so I went straight to the card, and the reference on the card said nothing about the Egyptian being a giant, from what I could see, it seemed that most of the giants still remaining in that time were in the Philistine camp.
